A:Answer Regardless of brand or manufacturer, Soundbars are universally compatible with almost any TV brand. As long as your TV and soundbar share a common connection method—such as HDMI ARC/eARC, optical audio, or Bluetooth—they will work together to deliver upgraded audio.
Connectivity for the LG 48" Class B5 Series OLED AI 4K UHD Smart webOS TV (2025), Model # OLED48B5PUA, includes pairing via Bluetooth, connection via its HDMI eARC port (HDMI 2), or via its Optical Digital Audio port.
Check what connectivity your SONOS ARK Ultra Soundbar has to determine how you can connect it to the TV.
HDMI eARC is the gold standard for audio quality. It transmits high-res formats like Dolby Atmos®, so if your soundbar features an HDMI eARC port, that will be the best connection to the TV. The HDMI eARC port can also be connected to the older HDMI ARC port, but to support high-res formats like Dolby Atmos®, both the soundbar and the TV must have HDMI eARC ports, since HDMI ARC does not support the high-res formats like Dolby Atmos®...^Ivan.
